#### BaseMemoryManager Class

**Core Functionality**:

```python
class BaseMemoryManager:
    def add_memory(self, memory_note): ...
    def remove_memory(self, memory_id): ...
    def update_memory(self, memory_note): ...
    def get_memory(self, memory_id): ...
    def retrieve_memory(self, query): ...
```

**Key Features**:

* Dual storage system (in-memory + ChromaDB)
* Atomic memory operations
* Automatic metadata synchronization
* Thread-safe access patterns

#### Memory Metadata Handling
